This is a guy from another forum I go to regularly (a Mercedes tuner forum)

At any rate, he too has a turbo C220 that he tracks. Except unlike mine, he built his engine to handle high boost. Here are some pics...

Exhaust after port & polish:


Intake after port & polish (but not totally finished yet):


Custom fab/install of MB factory oil jets from a late model Kompressor engine, which should help ensure that those sweet new Venolia pistons stay cool.


Intake with throttle body, compnents, and fuel rail. Note the nice new RC Engineering injectors, which allow a bit more flow than the stockers did


Cams in, and timing chain on! The 16 stiff new custom made Crower valve springs and titanium caps & retainers lurk just underneath.


The long-block back together again and ready to roll out for the install.
